Abstract
Systems, methods and devices for delivering stimulating energy with a lead having a directional electrode are disclosed. The lead includes a directional electrode having an electrically active portion configured to emanate stimulating energy from an exposed portion of the directional electrode. The lead also has an electrically insulating portion around at least part of the circumference of the lead. The electrically insulating portion is configured to insulate surrounding muscle and/or tissue from the stimulating energy when the lead is implanted in the patient.
Claims17
A lead for implantation in a patient, the lead comprising:
- a directional electrode having an electrically active portion configured to emanate stimulating energy from an exposed portion of the directional electrode;
- and
- an electrically insulating portion around at least part of a circumference of the lead, the electrically insulating portion configured to insulate surrounding muscle and/or tissue from the stimulating energy when the lead is implanted in the patient.
A method of implanting a lead in a patient, the lead having a directional electrode and an electrically insulating portion around at least part of a circumference of the lead, the directional electrode having an electrically active portion configured to emanate stimulating energy from an exposed portion of the directional electrode, the method comprising:
- placing the lead in the patient such that the electrically insulating portion of the lead is near an intercostal muscle of the patient and the electrically insulating portion insulates the intercostal muscle from the stimulating energy;
- and
- directing the directional electrode of the lead toward a heart of the patient.
A cardiac pacing system comprising:
- a lead implanted in a patient through an intercostal space and near an intercostal muscle in a region of a cardiac notch of the patient, the lead comprising:
- a directional electrode having an electrically active portion configured to emanate stimulating energy from an exposed portion of the directional electrode;
- an electrically insulating portion around at least part of a circumference of the lead, the lead implanted such that the electrically insulating portion insulates surrounding muscle and/or tissue from the stimulating energy.
